38 The Dairyman OCTOBER 2009
EFFLUENT
WHILE most water
treatments will take
iron out of bore water
supplies, Temple Water’s unique
product range (including the
Iron-Man, Iron-Master and
Rust-Buster Systems) also take
manganese out of the water,
which can cause systemic dam-
age to dairy machinery.
Temple Water Technologies
founder and managing director
Chris Temple said if manganese
was not removed it built up,
causing costly damage to pipes
and water pumps.
“Within a year you’ll start to
have issues with manganese
blocking pumps,” he said.
Mr Temple cited an example
of one farm owner who had to
replace a $5000 mineral dis-
penser due to manganese build
up.
Another farmer had to replace
250m of alkathene pipeline due
to it being plugged with man-
ganese deposits – even com-
pressed air cleaning couldn’t
save the pipeline.
Temple Water’s treatment sys-
tem removes both manganese
and iron through a completely
automated system.
Temple Water’s systems have
been on the market for nearly 10
years and have so far treated
over a billion litres of farm
water.
The treated water exceeds
MAF/Dairy regulations, and 98
per cent of the time has iron and
manganese levels 10 times lower
than national drinking water reg-
ulations.
Mr Temple said the system is
cheaper than buying water from
the town supply.
“Bore water treated correctly
through a treatment system will
cost less to provide clean clear
water to the farm than purchas-
ing the water from a rural
scheme.”
He mentioned Waikato dairy
farmer John Reekers, who milks
400 cows and uses 13,000 cubic
metres of water per year.
In 2007 the Hamilton City
Council charged one dollar per
cubic metre for water: it cost Mr
Reekers $13,000 per year. He
had a bore with a good flow rate,
yet the water contained high
iron, 7.65 parts per million
(ppm), and extremely high man-
ganese, 6.34 ppm and had a tur-

removed, it can cause costly
damage to pipes.
bidity of 57 NTU, which meant
the water was very murky.
These factors rendered it unus-
able.
After four years of buying
water Mr Reekers investigated
ways of using the bore.
Mr Reekers
consulted
Temple Water and decided the
most appropriate solution
would be to install an Iron-Man
system.
Mr Temple said because the
life of the treatment system was
in excess of 20 years, the cost of
buying the equivalent water
would be in excess of $200,000.
The initial start-up costs of the
Iron-Man system would be only
a fraction of the savings made.
Mr Temple said independent
laboratory testing confirmed
that after the installation of the
Iron-Man system, the iron lev-
els of the bore water at Mr
Reekers’ property were lower
than 0.01 ppm, manganese was
less than 0.005 ppm and turbid-
ity was 0.28 NTU.
“Mr Reekers’ water is now
better than MAF standards: it is
drinking water quality.”
Temple Water has since fur-
ther developed its system to
reduce running costs by up to
50 per cent. The unique filter
tank design reduces backwash
water volume by 40 per cent,
making it the lowest waste
water system in the country for
iron and manganese removal.
